Not doable whatsoever, as that would actually constitute mass murder rather than self-defense of each officer. Lawful and moral use of deadly force against any individual requires that that specific person first present deadly force themselves. So, to be clear, my overall point here is that bribing people from threatening deadly violence, is not as good as directly responding to such threats when and as they are made. Come to think of it, I'm not even quite sure why you made the leap that "allow riots to occur then respond to them appropriately" means "murder all the poor people".
